TheYamaha Model YBB-641 Professional Rotary Valve BBb Tuba features a rotary valve configuration for a traditional Teutonic sound with the kind of precise intonation and easy playability only made possible by modern engineering expertise. It is characterized by a warm dark sound with an abundance of tonal colors.

Large Diameter Bell

At 500mm, this is the largest bell among Yamaha Bb basses. Its size greatly improves dynamic range while delivering a stable sound that envelops the entire ensemble.

Bore Size

The bore size offers freer blowing with a moderate amount of resistance.

Fourth Valve Position

An ergonomically repositioned fourth valve offers improved playability and makes fast passages easier to play.

Repositioned First to Third Valves

After a thorough evaluation of valve positioning, a new design promotes a more comfortable playing posture.

Handrest Design

The semi-circular shaped hand rest makes the instrument easier to hold and reduces fatigue when holding the instrument for long periods of time.


Evaluating the angle of the mouthpiece led to a design that offers a more natural playing position.

Large Brace

A larger brace plate on the bell section delivers a moderate amount of resistance.

Hardcase: BBC-632
